Honey, I've lived in Michigan my whole life. I know 'what just happened'.

Lighten up. It's people like you on discussion boards who irritate me so much. Nobody can say anything without you jumping down their throat.

And over what? A little snow?

Get a life.

Chitaku points out something important. First, people hear that a storm is coming, so they decide against going places, even hours before the snow could even possibly start, so that they don't get "caught." And then, once it's snowing, people still tend to over-estimate things. If you have front wheel drive or 4-wheel drive, you can go anywhere, even if it takes twice as long...we never get those incredible snowfall rates and storm durations that will choke the streets (i.e. a lake effect snow storm in Buffalo or a nor'easter in Boston). The problem is the fear of other bad drivers, I think. Kind of justified. People in Michigan tend to be on the safe side, that's for sure.

http://radar.weather.gov/radar .php?product=N0R&rid=IWX&loop= yes

While the Detroit radar is out you can watch and and see the snow build in from the SW. The storm is moving slowly, and has hardly even come together yet. The possibilities for tonight and tomorrow morning are kind of ominous from what I hear.

The good news is our local forecast office is not over-doing things. They have some reasonable snowfall forecasts that they can adjust upwards if needed. (3-5 inches tonight and 3-7" tomorrow). Compare this the NE indiana bureau which is thinking Hillsdale County (borders on Lenawee) will see nearly twice as much as Lenawee. They're predicting 10-18" there. So that possibility is out there, but you shouldn't be banking on such a rare event beforehand.

Agreed on the ridiculous hysteria over snowfall...just think of our parents, grandparents and older driving the snowy streets of Detroit in the cars of yesteryear ...scary.

Especially when they outlawed chains on tires!

But I have to say people overestimate what AWD and 4WD, or a massive SUV will do for them in the snow. Sure you can tear past my small AWD vehicle and blast snow all over my windshield, but it takes longer for those guys to stop, and 4WD or AWD does not help you in a skid. Plus they're top heavy and it's real easy to go into a skid and tip.

The younger SUV drivers just don't get this...

Totally right. You will have a lot more traction and be a lot better off, but it doesn't give you permission to speed. When you're trying to brake and you start slipping, the 4wd doesn't help too much.

1254 PM EST SAT DEC 15 2007

.UPDATE...

...NOTE AVIATION DISCUSSION BELOW

HAVE WRITTEN A QUICK UPDATED DISCUSSION TO HIGHLIGHT ADDITIONAL
INFORMATION IN THE LATEST WINTER WEATHER MESSAGE /WSWDTX/. TWO
MAIN ALTERATIONS HAVE BEEN MADE. THE FIRST WAS TO UPGRADE/ISSUE
WINTER STORM WARNINGS FOR ALL OF THE TRI CITIES. THE SECOND WAS TO
SIGNIFICANTLY INCREASE EXPECTED TOTAL SNOWFALL ACCUMULATIONS FOR
THE IMPENDING WINTER STORM. THE MAJORITY OF THE COUNTY WARNING
AREA IS EXPECTED TO EXPERIENCE 8 TO 12 INCHES. FOR THE THUMB...10
TO 14 INCHES IS ANTICIPATED BY TOMORROW NIGHT. LOCALLY HIGHER
AMOUNTS ALONG THE LAKE HURON SHORELINE IS LIKELY AS THE SETUP FOR
LAKE ENHANCEMENT IS IMPRESSIVE. IN ADDITION...AN EXPECTED
FGEN/DEFORMATION BAND (WITH INCREASED SNOWFALL RATES) FACILITATES
THE NEED FOR LOCALLY HIGHER WORDING AWAY FROM LAKE HURON AS WELL.
NO CHANGES HAVE BEEN MADE TO TIMING.

Storms like this do crack me up though when I see people panic buying supplies. Ran out to the store today mostly to people watch and it was packed. Everyone had that panicked "must buy anything to eat and a shovel" look in their eyes since they didn't prepare ahead at all. Bring on the snow - been too long since we had a real storm.

Interesting that those weather bulletins are still printed in caps. I understand that older teletypes had no lowercase letters but you'd think they'd keep up with the times. Oh well.

This might be a good place to ask which weather web sites people prefer. http://www.intellicast.com/ seems pretty good. Here's their satellite loop and radar loop.

Any better ones available?

Attention all Doubting Toms:

Someone just told me that at the top of the hour, the TWC zoomed into Detroit and the meteorologist said we would get the brunt of this storm with up to 15 inches of snow possible.

Just something to add on to the thread.

It has started out here in the sticks along Lake Erie. Ground is now covered. I've got plenty to keep me busy indoors. So, let it snow, let it snow, let it snow!

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAND RAPIDS MI
340 PM EST SAT DEC 15 2007

LATEST UPDATE...ALL BUT AVIATION...

.SYNOPSIS...(340 PM EST SAT DEC 15 2007)
LOW PRESSURE DEVELOPING NEAR MEMPHIS WILL TRACK TO NEAR TOLEDO ON
SUNDAY. THIS WILL BE A MAJOR WINTER STORM FOR MUCH OF THE REGION.
THIS STORM WILL PULL AWAY FROM THE AREA LATER SUNDAY. HIGH PRESSURE
WILL BUILD IN FOR MONDAY.

&&

.SHORT TERM...
THE TIMING OF THE HEAVY SNOW AND POTENTIAL FOR BLIZZARD CONDITIONS
ARE THE MAIN CHALLENGES IN THE SHORT TERM. DECIDED TO START THE
WARNING EARLIER. THE MAIN REASON IS THAT THE DRY SLOT IS NOT
EVOLVING AS FORECAST...WITH SOME HEAVY SNOW IN EASTERN IA AT 18Z.
RADAR TRENDS ACROSS EASTERN MO THROUGH IL SHOW INCREASING
PRECIPITATION COVERAGE. VPZ WAS DOWN TO A HALF MILE AT 19Z. THE
SURFACE LOW WAS NEAR MEM AT 19Z AND DEEPER THAN ANY MODEL. THIS LOW
SHOULD TRACK TO NEAR TOL...WHICH IS FAVORABLE FOR SW LOWER MI TO SEE
A WIDESPREAD WARNING EVENT. THE 18Z RUC AND NAM SUPPORT THIS TRACK.
STRONGER MID LEVEL FGEN SUPPORTS THE HEAVIEST SNOW SOUTHEAST OF A
LINE FROM BIV TO MOP. LOCALLY IN EXCESS OF A FOOT COULD FALL.

WILL HOLD OFF ON A BLIZZARD WARNING. WINDS WILL BE ON THE INCREASE
LATER TONIGHT INTO SUNDAY. GUSTS OVER 30 MPH ARE LIKELY. THE RECENT
RUC RUN SUGGESTS GUSTS WILL STAY UNDER BLIZZARD WARNING CRITERIA.
GIVEN THAT THE SNOW WILL BE RELATIVELY DRY...CONSIDERABLE BLOWING
AND DRIFTING OF THE SNOW IS EXPECTED. EAST WEST ROADS SHOULD BE
ESPECIALLY HARD HIT...PERHAPS IMPASSABLE IN PLACES.

So it's not a Blizzard YET.

Well the Grand Rapids NWS covers the area west of Jackson and Lansing, Detroitrise. Let's keep it close to home.

It's still useful to look at the neighboring forecasts...the NE Indiana forecasts (which also cover Hillsdale) have predicted as much as 15" in their southern MI forecast areas, but in eastern Indiana they have mentioned sleet and freezing rain. All of their forecasts now have mentions of thundersnow.

Detroit is far enough north and will retain a NE wind flow, so I doubt we'll see a changeover. The system may be strong enough to give us thunder and lightning. Let's wait for the latest local discussion.

I noticed that they've upped the expected snowfall rates already. For 2-4 tonight and 3-7 tomorrow to 3-7 tonight and 4-8 tomorrow for Wayne and Washtenaw Counties.

This storm is happening at a low-impact time, though, in terms of business impact, commuting, etc. That is the good news. Everyone take it all in late tonight or tomorrow (just not on the road, hopefully). This could be something that's not exactly a once/year thing (rarer than that).

What are you talking about Mackinaw????

The branches do collaborate with each other, and DTX has been known to be very conservative with thier advisories.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
419 PM EST SAT DEC 15 2007

.SYNOPSIS...
-- Changed Discussion --STRONG LOW PRESSURE MOVING OUT OF THE LOWER MISSISSIPPI VALLEY WILL
MOVE TO CENTRAL OHIO BY SUNDAY MORNING. IT WILL THEN MOVE ACROSS
PENNSYLVANIA TO THE SOUTHERN NEW ENGLAND COAST BY SUNDAY EVENING
AS IT GETS CAUGHT UP IN A STORM DEVELOPING ALONG THE NORTHEAST COAST.
HIGH PRESSURE WILL BUILD INTO THE AREA MONDAY.-- End Changed Discussion --

&&

.NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --DEEPENING LOW STILL FORECAST TO MOVE TO CENTRAL OHIO BY 12Z
SUNDAY...SOME PLACE BETWEEN NAM POSITION OF FDY AND GFS ZZV
LOCATION. FURTHER WESTWARD TRACK OF NAM WOULD LIKELY SEE MORE OF
THE CENTRAL PORTION OF THE AREA CHANGE OVER TO PREDOMINATELY RAIN.
EVEN WITH GFS SOUTHERN PORTION FORECAST AREA IN OHIO LIKELY TO
CHANGE TO MOSTLY RAIN WITH MIXED RAIN NOSING UP CLOSE TO THE
CENTRAL LAKESHORE COUNTIES IN CLEVELAND AREA...WHILE EXTREME
NORTHWEST OHIO AND NORTHWEST PA STAY PREDOMINATELY SNOW OR SNOW
SLEET. WILL CONTINUE THE WINTER STORMS WARN AS IS THOUGH AREA FROM
MT VERNON...CAK AND YNG WILL LIKELY CHANGE TO RAIN BUT BESIDES THE
SNOW INTO EARLY EVENING THERE COULD BE BRIEF PERIOD OF MODERATE
FREEZING RAIN AND THEREFORE RELUCTANT TO DROP BACK TO ADVISORY.
SNOWFALL STILL CLOSE TO PREVIOUS FORECAST OVERNIGHT WITH 4 TO 6
INCHES NORTHWEST AND 2 TO 4 ELSEWHERE.-- End Changed Discussion --

&&

.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
-- Changed Discussion --WILL SEE QUICK CHANGE OVER OF THE MIXED PRECIP TO SNOW SUNDAY
MORNING AS THE LOW SHIFTS OFF TO THE EAST GETTING WRAPPED UP IN
THE EAST COAST LOW DEVELOPMENT. THE WINDS WILL BE ON THE INCREASE
SUNDAY. MENTIONING NEAR BLIZZARD CONDITIONS IN THE EXTREME NORTH
DEVELOPING. IT IS POSSIBLE THAT A BLIZZARD WARNING COULD STILL BE
NEEDED SUNDAY. TEMPERATURES WILL HOLD STEADY OR FALL. PLENTY OF
WRAPAROUND MOISTURE WITH THE LOW FOR SUNDAY. THE 700 MB LOW WILL
TRACK ACROSS THE NORTHERN COUNTIES AS THEY WILL GET THE HEAVIEST
SNOW...ESPECIALLY FROM CLEVELAND EAST BECAUSE OF ENHANCEMENT FROM
LAKE ERIE ADDED IN ON SUNDAY NIGHT.

HIGH PRESSURE RIDGE STARTS BUILDING IN MONDAY SO THAT WILL
DECREASE THE LAKE EFFECT SNOW QUITE A BIT AS THE DAY GOES ON AND
HIGH PRESSURE WILL BUILD ACROSS THE AREA MONDAY NIGHT...SOME LAKE
EFFECT COULD LINGER INTO THE EVENING EAST OF CLE.-- End Changed Discussion --

We're basically in a donut hole now of precip, but it should blow up like the atom bomb on Japan after sunset and especially towards midnight.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI
430 PM EST SAT DEC 15 2007

.SHORT TERM...THIS AFTERNOON THROUGH SUNDAY

THE LATEST WATER VAPOR IMAGERY AGREES NICELY WITH THE 12Z SUITE
DEPICTION OF A SOON TO BE NEAR NEUTRAL TILT TO THE FULL LATITUDE
TROUGH BISECTING THE CENTRAL UNITED STATES. WATER VAPOR IMAGERY IS
ALSO EXEMPLIFYING AN IMPRESSIVE BAROCLINIC LEAF WHICH SIGNALS THE
ONGOING...STRENGTHENING CYCLOGENESIS. CURRENTLY...A 1006 MB SURFACE
LOW IS LOCATED OVER THE MISSISSIPPI RIVER NEAR THE STATES OF
ARKANSAS/LOUISIANA/MISSISSIPPI . ALL INGREDIENTS AND FORCING
MENTIONED IN PREVIOUS FORECAST DISCUSSION ARE STILL PERTINENT (NO
MAIN CHANGES TO FORCING) AND WILL MAINLY DEAL WITH THE ONSET/CHANGES
TO PREVIOUS FORECAST IN THIS DISCUSSION.

UNTIL 00Z...EXPECT THE LULL TO CONTINUE IN REGARDS TO THE SNOW
ACTIVITY (EVERYONE WILL SEE A TRACE TO NOTHING/WHILE THE OHIO BORDER
MAY SEE UP TO A HALF INCH. LATEST PLAN VIEWS OF RH GUIDANCE SHOW DRY
AIR ALOFT INITIALLY WORKING INTO SOUTHEASTERN MICHIGAN AND
STRINGING/FILLING WITH TIME. ONE HAS TO TRAVEL INTO OHIO TO INDIANA
A SHORT DISTANCE TO SEE REPORTS OF MORE ROBUST SNOW. THIS WILL MOVE
IN AFTER 00Z AS THE EVENING PROGRESSES FROM SOUTH TO NORTH. BETWEEN
00-06Z...UP TO AN INCH OR 2 MAY FALL SOUTH OF M59. AN INCH OR LESS
NORTH OF M59.

THE LATEST MODEL GUIDANCE THIS MORNING LED OFF WITH THE NAM BRINGING
THE SURFACE LOW JUST A TOUCH FURTHER WEST TO ACTUALLY SLICING
BETWEEN TOLEDO AND CLEVELAND. THE GFS FOLLOWED A LITTLE MORE
WESTERLY AS WELL DEPICTING THE SURFACE LOW MAKING INROADS TO NORTH
CENTRAL OHIO BY TOMORROW MORNING. THIS LATEST NAM DEVELOPMENT
CONTINUES THE CLIMATOLOGICAL SIGNIFICANT LOW TRACK (ARKANSAS TO
NORTH CENTRAL OHIO) FOR HEAVY SNOWFALL ACROSS SOUTHEASTERN MICHIGAN.
IMPORTANT TO NOTE THE ECMWF CAME IN THIS AFTERNOON IN REASONABLE
AGREEMENT TO THE GFS. INITIALLY THOUGHT ABOUT ADDING MENTION TO SOME
POSSIBLE MIX MENTION FOR MONROE COUNTY OVERNIGHT AS POWERFUL LOW
WILL TRY TO WRAP WARM AIR IN. HOWEVER...WITH THE PRECIPITATION
RATES EXPECTED AND THE GFS/ECMWF CAMP TUGGING OUR EXPECTED LOW TRACK
OFF THE BORDER HAVE LEFT IT OUT. THE EVENING CREW CAN ASSESS THIS
THREAT THROUGHOUT THE EVENING.

THE HEAVIEST TIME PERIOD FOR SNOWFALL FOR MUCH OF SOUTHEASTERN
MICHIGAN WILL BE FROM THE APPROXIMATELY 4 AM TONIGHT THROUGH 4 AM
TOMORROW. DEEP LAYER FGEN AND OMEGA WILL SLIDE NORTH INTO THE STATE
BRINGING INCREASED RATES. EXAMINATION OF SOUNDINGS ALSO SHOWING
CONVECTIVE POTENTIAL TOMORROW AFTER DAYBREAK AS LAPSE RATES ALOFT
REALLY STEEPEN WITH 500MB CIRCULATION IN CLOSE PROXIMITY. IT IS
ANTICIPATED THAT A BAND OF HEAVY SNOWFALL WILL SETUP ACROSS PORTIONS
OF OUR CWA TOMORROW. THAT HAS FORCED THE MENTION OF LOCALLY HIGHER
AMOUNTS ADDED IN THE PRIOR WSW. THE CREW TONIGHT CAN EXAMINE THE
POTENTIAL/LIKELIHOOD OF ANY PERSISTENT MESOSCALE BANDING TEMPORALLY
AND SPATIALLY.

THE OTHER MAJOR PLAYER IN THIS SYSTEM WILL BE WINDS. AS THE SYSTEM
WINDS UP AND EJECTS EASTWARD TOMORROW....WINDS WILL BACK TO THE
NORTH AND STRENGTHEN...GUSTS OF AROUND 30MPH. THIS WILL ALLOW FOR
NEAR BLIZZARD CONDITIONS FOR ALL OF SOUTHEASTERN MICHIGAN WITH
COMBINATION OF HEAVY AND BLOWING SNOW. IT IS APPEARING LIKELY THE
THUMB REGION WILL REQUIRE AN UPGRADE TO A BLIZZARD WARNING FOR
TOMORROW. HOWEVER...WILL HOLD OFF A TOUCH LONGER SO LATEST MODEL
GUIDANCE CAN BE EXAMINED THIS EVENING/OVERNIGHT...AND TO PRESERVE
THE SHORT-FUSED IMPACT OF HEIGHTENED AWARENESS.

SUMMARY OF CHANGES TO THE HEADLINES. IN COORDINATION WITH
SURROUNDING OFFICES HAVE MOVED THE START TIME OF THE WARNINGS TO
4PM/THIS ISSUANCE. AGAIN...SHOULD BE NOTED THE BULK OF THE SNOW
WILL HOLD OFF UNTIL AFTER MIDNIGHT...LATER YET TO THE NORTH. TOTAL
STORM ACCUMULATIONS EXPECTED...MOST EVERYONE 8 TO 12 INCHES WITH
LOCALLY HIGHER AMOUNTS...AND 10 TO 14 INCHES FOR THE THUMB WITH
LOCALLY HIGHER AMOUNTS

I was just imploring you to wait for this:
http://www.crh.noaa.gov/produc t.php?site=NWS&issuedby=DTX&pr oduct=AFD&format=CI&version=1& glossary=1
Chill yo! I didn't say they didn't collaborate, but it often takes time for that process to occur.

Their forecast is on track, they say. Snow finally overspreads the area south of M59 this evening, and then blows up like you've said. Bands of heavy snow will linger over SE Michigan from 4am-4pm. If rates are any higher than expected over that duration, we'll have a real treat.

Actually, I was already waiting on their discussion.

Anyway, I was just imploring you guys to not keep your hopes up for a Blizzard Warning. The forecast Wind and Snow is only bordering the criteria for a Blizzard. That does not mean that near-blizzard conditions won't occur though.
